Radionuclides of bulk and terrigenous surface sediments in the Southern Ocean
Sr and Nd isotopic compositions of Late Quaternary surface sediment and sediment cores from the south Atlantic and southeast Pacific sectors of the Southern Ocean are used to... -
Radionuclides in sediment cores of the Atlantic sector of the Southern Ocean
We present time series of export productivity proxy data including 230Thex-normalized deposition rates (rain rates) of 10Be, dissolution-corrected biogenic Ba, and biogenic opal... -
Abundance and opal input of radiolarian species of two sediment cores from th...
Radiolarian-based paleoceanographic reconstructions generally use the abundance of selected radiolarian species. However, the recent focus on the opal flux and the development... -
Radionuclides of sediment cores and a sediment trap in the Weddell Sea
The scavenging of 230Th and 231Pa was investigated in the central Weddell Sea by combining results from a sediment trap and three sediment cores. Scavenging of both... -
Paleomagnetic measurements of 10 sediment profiles from the Antarctic contine...
Die im Rahmen des zweijährigen Forschungsprojekts über paläomagnetisch-sedimentologische Analysen sedimentärer Zyklen in der Weddell See und ihre stratigraphische Interpretation... -
Organic carbon and biomarker record from the Laptev Sea continental margin
In order to understand the processes controlling organic carbon deposition (i.e., primary productivity vs. terrigenous supply) and their paleoceanographic significance, three... -
Susceptibility of sediment cores of the Laptev Sea
Marine geological investigations were performed across the Laptev Sea continental shelf and slope. Thirty sampling sites were selected covering a depth range of ca 3500 m.... -
AWI Bathymetric Chart of the Gakkel Ridge (AWI BCGR) (Scale 1:150,000)
The 1 : 1,500,000 AWI Bathymetric Chart of the Gakkel Ridge (AWI BCGR) has been developed from multibeam data measured during the Arctic Mid-Ocean Ridge Expedition in 2001... -
Sedimentology of 2 profiles from the Scotia Sea
Geochemical and mineralogical compositions of modern and Late Quaternary marine sediments from the Scotia Sea trace sources and transport paths of terrigenous sediment. We... -
Sea surface temperature reconstructions of sediment cores from the Atlantic s...
Late Quaternary summer sea surface temperatures (SSTs) have been derived from radiolarian assemblages in the East Atlantic sector of the Southern Ocean. In the subantarctic and... -
High-resolution magnetostratigraphy of sediment cores from the Greenland Sea
High-resolution magnetostratigraphic analysis of three sediment cores from the base of the volcanic seamount Vesteris Banken in the Greenland Basin and one from the Jan Mayen... -
Magnetostratigraphy of sediment cores from the Greenland Sea
High-resolution magnetostratigraphic analysis of three sediment cores from the base of the volcanic seamount Vesteris Banken in the Greenland Basin and one core from the Jan... -
Radionuclides in the Weddell Sea
228Ra and its granddaughter 228Th were measured on a N-S transect from 45's to the Antarctic continent across the Antarctic Circumpolar Current (ACC) and the Weddell Sea. The... -
Radionuclides in the water column at stations near the Antarctic Polar Front ...
Vertical profiles of dissolved and particulate 230Th and 231Pa were obtained across the Antarctic Circumpolar Current (ACC) in the southern Atlantic. North of the Polar Front,... -
Age determination of sediment cores of the southeastern Weddell Sea, Antarctica
On the continental margin of the southeastern Weddell Sea, Antarctica, several channel-ridge systems can be traced on the eastern side of the Crary Fan. Swath mapping of the... -
Organic geochemistry on sediment profiles from the Arctic Ocean
During the ARCTIC '91-Expedition with RV 'Polarstern', several Multicorer and Kastenlot-cores were recovered along a profile crossing the eastern part of the Arctic Ocean. The... -
Physical properties and age determination of sediment cores from the Hinlopen...
Integrated interpretation of multi-beam bathymetric, sediment-penetrating acoustic (PARASOUND) and seismic data show a multiple slope failure on the northern European... -
Recent benthic foraminifera of the Scotia Sea and Argentine Basin
We investigated 88 surface sediment samples taken with a multiple corer from the southwestern South Atlantic Ocean for their live (Rose Bengal stained) and dead benthic... -
Sedimentology at the continental margin of the southern Weddell Sea
During four expeditions with RV "Polarstern" at the continental margin of the southern Weddell Sea, profiling and geological sampling were carried out. A detailed bathymetric... -
Oceanographic profiles and ice rafted debris in sediments from the Scoresby S...
Holocene glacimarine sedimentation associated with fast-flowing outlet glaciers draining the Greenland Ice Sheet is investigated using sedimentary and acoustic data from inner...
